You could well be right ,that I'm getting Tattoo you and Emotional rescue mixed up , but then that does not really say alot for the songs that they were writing at the time.
As for the other albums I don't know, but I have
always been led to believe that they consisted of songs recorded at sessions for those albums.
If what you say is it destroys alot of the legend that
Exile was recorded in the basement at Nellcote.
